GROUPE, OFPHILADELPHIA, PENNSYLVANIA CABLE SUPPORT Thisinvention relates toimprovements in cable supports orhangers adaptedto be connected'atintervalsto a supporting or messenger-wire and to receive and support .acable,.thesupporting; or messenger wire being-formed of a multiplicityof wire strands twisted around, a central or core strand.

The twisted strandsof the supporting'or messenger-wire provides it' withrelatively large and small: diameters in alternate-sue cessi'on',' whichprovide expanded portions at the large diameters and contractedqportlonsat the small'diameters in alternate'succes- 'sion, on lines which extendparallel to the longitudinal'axis of-the'supportin'g wire.

Gable supports have been constructed to cooperate with the shouldersformed by the V expanded portions of the supporting-or messenger wireto; prevent displacement of the cable support longitudinallyof=t-hesupporting-wire when a cable is-drawn-through'the support, and,at times, difficulty has i been experienced in keeping all the cablesupports in theirproper'places on the supporting wire due toirregularities in the parts of the cable support'on the supporting wireor both or unusual strains or other causes-while the cable to besupported by the cable supports is being drawn therethrough. I

My present invention aims to overcome the aforesaid difficulty to alargeextent and to lessenthe danger of dislodging the cable -sup'-'ports from their proper positions on the supporting-or messenger wireduring, the cable drawing operation, and I accomplish my ob"- ject bytheprovision'of a cable support of novel construction which will moreeffectually grip and co-operate'with the supporting wire for theprevention of its displace- Figure 3 is-a-top view of the parts shown inFig. I

Referring to the drawing,- 2 designatesthe supporting or messenger wireand 3' the cable support thereon.

Thesupporting wire 2 comprises a cen: tral or core strand and outer.strands lying side by-side in close relationship and twisted in spiralOr -helical form aroundthe core strand. The supporting I wire 2 hasrelatively large diameters? and small diameters, in alternate successionwhich providev the sup porting: wire with expanded portions atthe largediameters 7 and contracted portions-at the small diameters, in alternatesuccession on lines which extend parallel to the axis of the supportingwire 2.

arms 9 and 10. respectively, anarm' 13 extending from the hook 11 and anarm 14 extending: from and forming in eifect, a continuation of. the arm13.

The hooks 11 and 12 are disposed opposite to each other and they embracethe supporting wire 2 from opposite sides thereof to connect the cablesupport thereto in 'a manner t0. permitit to serve asa supportforsuspending a cable. indicated-at 27 in Fig. 1,.from the supportingwire.

The loop 8 isformed by a flatwise bend-in the wire formingit and itextends transverse lv' of the supporting wire 2 for the reception of thecable 27, and thejdiverging arms -9.'and

10 space the hooks 11 and 12 longitudinally of the supporting wire.

The hooks 11 and 12 are formed by flatwise bends in the wire formingthem. They are provided with bottom parts 16 and 17 which extend underthe supporting wire 2, and top parts 18 and 19 which extend over the supporting wire 2, respectively.

The arm 13 is joined to the top part 18 of the hook 11 by an abruptedgewise bend 15 in the wire forming them, such edgewise bend beinglocated over the supporting wire 2. The arm 13 extends from the top part18 of the hook 11 downwardly and outwardly over one side portion of thesupporting wire 2 and in a direction away from the space between thehooks 11 and 12.

Thearm 14 is joined to the arm 13 by an abrupt edgewise bend 20 in thewire forming them, and the arm 14 extends downwardly and inwardly fromthe arm 13 and under the side of the supporting wire 2 over which thearm 13 extends.

The arm 13 is provided with an elbow 21 formed therein by a flatwisebend in the wire forming the arm to cause the arm 13 and the lowerportion of the arm 14 to occupy particular positions with relation toparts of the supporting wire 2 as and for a purpose presently explained.

The arms 13 and 14 are located on the same side of the supporting wire 2and the curved portion of the hook 12' connecting the top portion 19 andbottom portion 17 thereof, and on the opposite side of the supportingwire 2 to the curved portion of the hook 11 connecting the top portion18 and the bottom portion 16 thereof.

In applying the cable support3 to the supporting or messenger wire 2,the cable support is turned and manipulated by hand to pass the arms 13and 14 over the supporting wire 2 and down opposite to one side thereofin advance of applying the hook 11 to embrace the wire 2 from theopposite side thereof. After the arms 13 and 14 and hook 11 have beenapplied to the wire 2, the hook 11 fits the wire 2 sufficiently loose toallow it to rock enough to permit the hook 12 to be moved under the wire2 while the hook 11 is being applied thereto. During and after theapplication of the hook 11 to the wire 2, the hook 12 is moved beneaththe wire 2 in the direction of the arrow 22 by springing the loop orbody 8 of the support 3 until the free end of the hook 12 clears theside of the wire 2 on which the arrow 22 is located; whereupon the hook12 is raised and placed in embracing engagement with the wire 2, asshown in the drawing, while the loop or body portion 8 of the support 3is permitted to spring back toward its normal condition. hen the hook 12is thus applied to the wire 2, the loop 8 is sprung in opposition topressure of the hook 11, in the direction of the arrow 23,

against the wire 2, and in opposition to pressure of the arms 13 and 14,in the direction of the arrow 24, against the wire 2.

Before the cable support 3 is applied to the supporting wire 2, thehooks 11 and 12 are spaced apart, laterally of the wire 2, as shown inFig. 4, and the respective sides of the loop 8 are more widelyseparated, so that after the support has been applied to the wire 2, thetendency of the loop 8 to resume its normal condition, as shown in Fig.4, will cause the hooks 11 and 12 to be pressed firmly against the wire2 in the directions of the arrows 23 and 22, respectively, and willcause the arms 13 and 14 to be pressed firmly against the wire 2 in thedirection of the arrow 24.

The sides of the arm 14 and that portion of the arm 13 below its elbow21 which face the supporting wire 2 are substantially straight and setat such angles with relation toeach other and to the wire 2 that whenthe cable support 3 is applied to the supporting wire 2, as shown inFigs. 1, 2 and 3, the arm 14 and the lower portion of the arm 13will'embrace one of the strands of the wire 2 and enter contractedportions of the wire 2 below and above the embraced strand,respectively, and thus occupy positions to encounter expanded portionsof the supporting wire 2 and be thereby prevented from being displacedlongitudinally of the wire, when a cable is drawn through the cablesupport.

The relation of the arm 14 and the lower portion of the arm 13 to thesupporting wire 2, as shown and described, is such that should a cablebeing drawn through the cable sup port in the direction of the arrow 25in Fig. 2 tend to cant the support in that direction, such tendency willcausethe arm 14 and the upper portion of the hook 11 to be forced intofirmer engagement with thewire 2; and that should a cable being drawnthrough the support 3 in the direction of the arrow 26 in Fig. 2 tend tocant the support in that direction, such tendency will cause the lowerportion of the arm 13 and the hook 11 to be forced into firmerengagement with the wire 2. As there is nearly always a tendency to cantthe cable support while a cable is being drawn therethrough, theutilization of such tendency to effect firmer grip of either or bothofthe arms 13 and 14 upon the supporting wire 2 is a factor ofconsiderable importance in preventing displacement of the cable support3 on the supporting wire 2, independently of the relation of the arms 13and 14 to the expanded and contracted portions of the supporting wire 2.

Either the space between the parts 16 and 18 of the hook 11 or the spacebetween the parts 17 and 19 of the hook 12 or both are preferably madeless than the diameter of the expanded portions of the supporting wire2, so that the hooks 1.1 and 12 may embrace contracted portions of thewire 2 and be prevented by expanded portions thereof from beingdisplaced longitudinally of the wire.
